TRACE-CARRIER.

SPECIFICATION forming part of Letters Patent No. 694,336, dated. February 25, 1902.

Application tiled July 13,1901.

To all whom, it may concern,.-

Be it known that I, THOMAS D. THURMOND, a citizen of the United States, residing at Forsyth, in the county of Monroe and State of Georgia, have invented certain new and useiul Improvements in Trace-Carriers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to trace-carriers and it has for its object to simplify and cheapen the construction of the carrier and to facilitate the manipulation of the parts by means of which the carrier is adj ustably connected with the back-band.

To enable others to fully comprehend my invention, I will describe the same in detail, reference being had to the accompanying drawings, in which- Figure 1 is a face View of the carrier proper. Fig. 2 is a like View showing the pigtail or curled trace-hook in position for removal from its support. Fig. 3 is a face view of the complementary element or locking-plate of the carrier; and Fig. 4 is a cross-section on line a: of Fig. 1, showing the carrier applied to a back-band.

The main plate or carrier proper is a plain oblong plate p, having a longitudinal slot 2 so located as to form arelatively narrow crossbar 3 and a relatively wide cross-bar 4. The wider cross-bar 4, about midway of its length, hasa corrugation 5, forming on the rear face of the plate a recess 6 of sufficient width to accommodate the head of the trace-hook c and allow its free rotation in bearing 8, said hook being curled and known as the pigtail trace-hook, whereby the accidental slipping oif of the trace-chain is prevented. The recess 6 in plate p is of sufficient depth to contain the aforesaid head of hook c and prevent said head from projecting beyond .the rear face of the plate p, as clearly shown in Fig. 4.

In order that the curled hook c may readily be introduced into or removed from its bear- Serial No. 68,191. (No model.)

ling S in the corrugatiori or bulge 5 of plate p,

I cut away a portion of the inner edge of crossbar 4 along the slot 2 at an angle to a horizontal in a lateral direction'to form the inclined face 9, which terminates in an arcuate portion 10, so that the trace-hook c can be positioned relatively to its bearing, as shown in Fig. 2, and turned or screwed out of its said bearing, which would otherwise be very difcult if not impossible. The complementary or lock plate lis also a plain oblong plate P and has a longitudinal slot 12 so located as to form a lower relatively narrow cross-bar 13 and an upper relatively wide cross-bar 14, the arrangement of these narrow and wide crossbars of plate P being the reverse of the arrangement of the corresponding cross-bars of plate p, so that when one end of the backband B is passed through the slot 2 of plate p, then through the slot 12 of plate P over narrow cross-bar 3 of said plate P, and again through slot 2 of-plate p the wider cross-bar 14 of said plateP will project beyond the outer edge of plate p, and thus provide a handhold, whereby the plate P may be seized and turned to release the band when it becomes necessary to adj ust the trace-carrier.

In theconstruction described it is obvious that the greater the strain on the band B the more iirmly will it be gripped by the lockplate P, whose narrower cross-bar 13 bridges the'slot 2 in plate p, which slot is much wider than the slot 12 in lock-plate P, so as not only to accommodate the two thicknesses of the back-band B,lout so that the latter may readily follow the movement of the lock-plate when turned from right to left, Fig. 4, and release the back-band. On the other hand, the wider cross-bar 14 of the lock-plate serves as a bearing and brace for the narrow weaker crossbar 3 otthe carrier-plate p when in use, so that all danger of said weaker cross-bar breaking or bending under the strain of the backband is avoided.

From what has been said and as shown in the drawings it will be obvious that my improved trace-carrier is ofthe simplest construction, hence can be manufactured at a very low cost. It is devoid of gripping-teeth, hence does not wear the back-band as rapidly IOO as when such teeth are made use of to grip the back-band, and the efficiency of the tracecarrier is equally as great as any known to me.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

l. A trace-carrier com prisin g a carrier-plate proper, slotted longitudinally to form a relatively wide cross-bar and a relatively narrow cross-bar, and a trace-hook pivoted about the longitudinal center of and in a bearing in said wider cross-bar; in combination with a lockplate having a narrow and a Wider cross-bar, said Wider cross-bar designed to form a bearing for and project beyond the narrower crossbar of the carrier plate when applied to a back-band as described, for the purpose set forth.

l 2. Atraee-carrier,cornprisingacarrier-plate proper, slotted longitudinally to form a narrow and a wider cross-bar, said wider crossbar provided about midway of its length With a recess in its rear face, with a hole in said recessed portion and with the cut-away portion, 9, l0, and a curled trace-hook pivoted in the aforesaid hole with its head in the recess of the plate; Ain combination with a slotted lock-plate cooperating with said carrierplate to lock the same to a back-band, for the purpose set forth.

In a trace-carrier, the carrier-plate p provided with the transverse recessed portion 5 having a hole or bearing S; in combination with a trace-hook pivoted in said bearing with its head 7 in the aforesaid recess, for the purpose set forth.

4. In a trace-carrier, the longitudinallyslotted carriereplate p having a portion of the cross-bar on one side of the slot cut away to form the inclined face 9; in combination with a curled or pigtail trace-hook pivoted about midway of and in the aforesaid cross-bar, and having a head 7, formed on its shank, substantially as and for the purpose set forth.

5. In a trace-carrier, a longitudinally-slotted plate having a narrow cross-bar 3 on one side and a widerycross-bar 4 on the opposite side of its slot, and a trace-hook pivoted in said Wider cross-bar; in combination with a longitudinallyslotted lock-plate having a wider cross-bar 14 on one side and a narrower cross-bar 13 on the opposite side of its slot,- substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

THOS. D. TIIURMOND.
